Overview and Dimensions

Galaxy S9 was released by Samsung on Friday, March 9, 2018 and is powered by Android OS. By default, the device is shipped with a web browser — Chrome. Device dimensions are 68.7×147.7×8.5 millimeters (2.7×5.81×0.33 inches)1. The device weighs 163 g.

Galaxy S9 has a Super AMOLED display with a 5.8-inch screen (84.8 cm2, 18.5:9 aspect ratio), and an approximately 83.6% screen-to-body ratio. The display is a touch screen, meaning that it supports touch events - interactions using a finger or stylus.

1 - Property is displayed as width × height × thickness.

Screen size, Viewport & Pixel Ratio

Galaxy S9 has a 5.8-inch screen with a screen size (resolution): 1440px × 2960px , 360px × 740px viewport1, and a CSS Pixel Ratio of 4.

1 - Property is displayed as width × height.

Screen size (resolution) is the number of physical pixels present on a screen.

Viewport or Viewport size is the number of software pixels (CSS pixels) present on a screen. Usually, viewport size displays as viewport width in pixels to viewport height in pixels.

Device Pixel Ratio (DPR) or CSS Pixel Ratio is the ratio between the physical pixels (screen size or resolution) and CSS pixels (viewport). Depending on device specification, one CSS pixel can equal one or mode physical pixels. Modern devices have screens with high pixel density resulting in the difference between screen size (resolution) and viewport.

Summary:
Screen Size (Resolution) = Viewport size × Device Pixel Ratio.
Viewport size = Screen Size (Resolution) / Device Pixel Ratio.
CSS Pixel Ratio = Screen Size (Resolution) / Viewport size.

Key points for development and testing

Before you start web development or testing, check that the web application supports a responsive viewport by using a viewport meta tag:

You can inspect this tag in the head section of an HTML document on Galaxy S9 right in the Blisk app. If this viewport tag is missing, the web application will not be responsive and will overflow the screen, hiding the content from users and leading to a bad user experience.

The form factor of the device represents its primary orientation as a portrait. Landscape orientation is popular on Galaxy S9 as well and should be seriously considered when you develop or test web applications on any mobile.

You also need to consider that the users will manipulate your web application on Galaxy S9 with a finger and stylus because this device has a touch screen that supports touch events. It is important to remember, that users may interact with multiple fingers (multi-touch) and gestures: single tap, multi-tap, swipe, pinch, stretch, zoom, etc. The users are highly likely to use gestures on small touch screens because of seamless interaction and great user experience.
